【Abstract】 The carburization rate can be increased 20% compared with the conventional carburization process by using RE catalyzed carburizing.When the carbon potential in the region Ⅱ was increased to 1.3%,and adding RE,the carburization rate can be increased 31% compared with the conventional process and the microstructure can be improved remarkably.This process has been used in production more than a year,and it is confirmed that this is a simply operational,stable and reliable technology.It shows remarkable economical benefits.更多还原
